About the Typing WPM Calculator

Typing WPM is treated here as a quantitative relation between Total Characters Typed, Time Taken and Number of Errors and Gross WPM, Net WPM, Accuracy and Skill Level.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
Gross WPM = (Characters Typed / 5) / Time in Minutes
Net WPM = Gross WPM - (Errors / Time in Minutes)
Accuracy = ((Characters - Error Characters) / Characters) x 100
Standard: 1 word = 5 characters

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

Gross WPM = (Characters Typed / 5) / Time in Minutes
Net WPM = Gross WPM - (Errors / Time in Minutes)
Accuracy = ((Characters - Error Characters) / Characters) x 100
Standard: 1 word = 5 characters

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: 1250 characters in 5 minutes, 3 errors

Inputs

characters_typed: 1250 time_minutes: 5 errors: 3
Gross WPM: 50 WPM. Net WPM: 49 WPM. Accuracy: 98.8%. Skill Level: Below average - improvement recommended

With Total Characters Typed = 1,250, Time Taken = 5 and Number of Errors = 3 as the stated inputs, the result is Gross WPM = 50 WPM, Net WPM = 49 WPM and Accuracy = 98.8%. Each value corresponds to the declared output fields.

Example 2: 1800 characters in 3 minutes, 1 error

Inputs

characters_typed: 1800 time_minutes: 3 errors: 1
Gross WPM: 120 WPM. Net WPM: 120 WPM. Accuracy: 99.7%. Skill Level: Professional / Expert typist

With Total Characters Typed = 1,800, Time Taken = 3 and Number of Errors = 1 as the stated inputs, the result is Gross WPM = 120 WPM, Net WPM = 120 WPM and Accuracy = 99.7%. Each value corresponds to the declared output fields.

Example 3: 600 characters in 5 minutes, 10 errors

Inputs

characters_typed: 600 time_minutes: 5 errors: 10
Gross WPM: 24 WPM. Net WPM: 22 WPM. Accuracy: 91.7%. Skill Level: Beginner - significant practice needed

With Total Characters Typed = 600, Time Taken = 5 and Number of Errors = 10 as the stated inputs, the result is Gross WPM = 24 WPM, Net WPM = 22 WPM and Accuracy = 91.7%. Each value corresponds to the declared output fields.

Example 4: Student taking notes: 900 chars in 4 minutes, 5 errors

Inputs

characters_typed: 900 time_minutes: 4 errors: 5
Gross WPM: 45 WPM. Net WPM: 44 WPM. Accuracy: 97.2%. Skill Level: Below average - improvement recommended

With Total Characters Typed = 900, Time Taken = 4 and Number of Errors = 5 as the stated inputs, the result is Gross WPM = 45 WPM, Net WPM = 44 WPM and Accuracy = 97.2%. Each value corresponds to the declared output fields.
